The design of the ''Tennessee''-class was a considerable improvement over that of earlier U.S. Navy battleships. The two ships featured the same twelve 14"/50 guns and armor protection as in the preceding [[New Mexico-class battleship|''New Mexico''-class]], and had a similar hull. However, their newly developed four-layer anti-torpedo system, built into the hull sides, and the revised arrangement of boiler and engine rooms permitted by their turbo-electric machinery greatly enhanced their combat survivability. Increased elevation of the main-battery guns and improved gunfire directors atop heavier "cage" masts allowed greater battle ranges. All of the five-inch secondary battery guns were now in the superstructure, where they were less vulnerable to heavy seas. | The design of the ''Tennessee''-class was a considerable improvement over that of earlier U.S. Navy battleships.
